Background: Endodontically treated teeth lose a large proportion of their structure due to trauma and caries and during endodontic treatment. As a result, they have low physical properties, fracture resistance, and esthetic appearance. The study aims to evaluate the anti-oxidant efficacy of sodium thiosulphate, citric acid and gallic acid on the recovery of shear bond strength to pulp chamber dentin treated with NaOCI & EDTA. Methodology: 50 single rooted second premolars were divided into 5 groups (n=10); Positive control received no treatment; negative control received only irrigation treatment, while the other two experimental groups were treated with their respective anti-oxidant following the irrigation. All the samples were then cured with composite and subjected to SBS test under a universal testing machine. Statistical analysis: ANOVA & Post hoc tukey were used with P <0.5. Results: Anti-oxidant groups showed a greater mean SBS value than the negative control, comparable to positive control. The sodium thiosulfate group showed the highest value with a significant difference from the negative control group. Conclusion: Both the anti-oxidants used were able to restore the Shear bond strength of pulp chamber dentin altered due to endodontic irrigants. Hence, possesses great potential in its clinical implication.
